Another possible function from F&O:
the function is fn:encode-for-uri
Peter also overloads "+" as string concatenation and uses expressions in
the CONSTRUCT template.

Hi,
I am not sure what the progress has been on the (very useful)
extension to make it possible for SPARQL to create new URI/IRIs from
literals/variables [1] but it would be nice if the discussion could
also include something about a function for string transformation to
encode strings so that the URIs are valid.
For example it would be nice to be able to do something similar to the
following pattern using a IRI/URI creation facility,
CONSTRUCT
{ ?s <skos:prefLabel> ?label . ?s <myLibrary:hasAlternateURI>
IRI("http://otherlibrary.example/"+example:percentEncode(?label)+"/lang/"+example:percentEncode(lang(?label))}
WHERE
{ ?s <skos:prefLabel> ?label . }
Cheers,
Peter
